STOVE.

To: alliwhom' z'ltimwy1 concern:

Be it: known that I, ABRAHAM" LIBERMAN, a citizen of Poland, residing atCleveland; inthe county of Cuyahoga and State of Ohio,- have tinventednew Y and useful lm provements in Stoves, of which the-tollowing is a=-specification.

My present invention pertains to safety appliances for stoves of thenatural or manufactured gas-type and it contemplates the provision ofmeans whereby it through neglect or otherwise the flame from the burnershou ldbe casually extinguished the gas willitravelto the chimney ofthe-stove and no-t ba'c'k up through the gas outlets into the room orapartment.

The invention further contemplatesthe provision of means in use inconnectionwith.

Figure-3 is a view taken inthe planein-- dicated by the line 83 ofFigure 2 and looking in the direction'ofthe arrows; I

Figure 4 is a View showing in detail the interior ring of the exteriorburner ring and the vent from the ring.-

F igurefi isa sectional view taken in the plane indicated by the line 55of Figure 3 and looking in the'direction of the arrows.

Figure 6 is a top plan view of one'o't my novel burner rings.

Similar numerals of referenced'esignate corresponding parts inall theviews of the drawings.

For the purpose of illustration I show the stove 1 having the burnerplate 2 on which the supports 3 for the burner rings rest, and I alsoshow the ordinary inlet pipe 4 having the well known cocks 5 and an opendoor 6 as illustrated together with the Serial No.- 696 360 pipe-7 andgas-cock 8 for feed -of gas to the oven;

Arranged to" rest 011* the burner plate 2 immediately below the topofthestoveand atv the I ordinary T well known position are my novelburner rings 9 that are by preference formed ofan upper andlower-semicircular portions" 10 and 11; I have" designated the ringsasfawhole by 9 and the portions that go to makeup theringbylO'and 11 forthesake of clearness and these sections are bolted or otherwise secured" bv1ne-ans of the fastenings '12. The upper portion 11 ispro" vided withthe outlets 1 18 that are --arranged oii center for an importantpurposeherein after set forth and adapted 'to be-encased by the upper and lowerportions-1O and- 11 of: the ring 9 is a circular conduit- 'l l-flthatis: provided with the nibsor-proje'ctions -15 that are conical shape asshown e and? are hollow throughout and the said nibs orprojee tionsenter an apertureor opening in the conduit 14 and'at' the upper sidethereof that in'turn registers withapertures in the burn er ring9.

It will be noted that I pro'videcteedpipes- 16 from the inlet pipe 5 totheburner rings and it will be noted further that at the rear of theburner ring are three more or less nibs 17 that take into a conicalmember 1.8 before passing to the outlet pipes 19. Particular attentionisdireetedtothefa'ct' that I construct the pipes -16flan'd '19" so thatgas to and from the burner rings-must; take" a tortuous course and thisis do-nein order to assist in'bafliing the return of the gas to theburner after leaving the burner which will be clearly set forth inthepractical operation of the invention.

It will be further seen that-some oil the burners'are providedwithoutlet pipes- 20 and these pipes are additionally bent'a's';indicated by 21 soas to balhethe returirof ,QEIS;

The pipes 19 and 20. eventually terminate into and extenddownwardlyalongthe rear of a stove and rest in a Qhinmey'QQth'at isprovided at its lower 'endwith a'-seal- 23. This construction ofs'eal'is duplicated in the oven portion of the chimney as indicated by23 and is open to permit the gas from pipe 50 to travel directly intothe conical portion 24, by means of opening 29' and arranged in thechimney 22 are conical shaped members 24: and 24: open throughoutONE-FIFTH TO JAKE their lengths as indicated by 25, 26', 27' and 28 andcommunicating one with the other and at its lower end a draught aperture25 is arranged in the chimney. Mounted on the chimney 22 is a cap 26that is arranged in the draught outlet 27 and has an upstanding tube 28that terminates within the chimney 29.

The burners 9 may be constructed as illustrated in Figures 3 and i but Iprefer that they be provided with the central curved portion 30 as inFigure 6. The purpose of the curving, twisting and bending of the pipesof this improvement is in order to baffie, as much as possible, thereturn of unburned gas.

In the practical operation of the device, gas enters the inlets 16 underpressure and goes into the interior 9 of the rings 9 and is suckedthrough the nibs 15 and out of conduit 14 into the registering burneropenings 13. If, however, the light of the burners were accidentlyextinguished, the nibs being directed at the angle disclosed andstaggered as shown would cause the-gas to travel within the ring at 9until it reached the vent 18. The gas would then pass into the pipes 19or 20 as the case may be and from there into the chamber surrounding theconical shaped portions 24 of the chamber or chimney 22. The gas willstrike the seal 23 and will travel around the conical portion 24: untilit reaches the upper end of the conical portion when it will be forcedby air entering the lower end 25 of the chimney 22 into the tube 28where it is carried off by the chimney 29. 1

In Figures 1 and 2 I have shown the oven as equipped with my novelburner and the construction of this burner and its appurtenances issimilar to that of the burners above referred to and it will be notedthat the take off pipe 50 is provided with a kink 51 and the operationof this burner is similar to that of the ones before set forth.

It will be manifest from the foregoing that if at any time throughcarelessness or otherwise the gas should become extinguished theliability of asphyxiation due to escaping gas is eliminated because ofthe fact that the gas cannotenter the room and pass through the openings13 of the burners 9 if a burner is accidentally extinguished.

My invention is extremely simple in construction and arrangement andcomprises no delicate parts such as will become inoperative after ashort period of use and in the future practice of the invention I do notcare to be restricted to the exact construction of elements as set forthand illustrated for the reason that I reservefi to myself the right tomake such changes and modifications as fairly fall within the scope ofthe claims appended.

Having described my invention, what I claim and desire to secure byLetters Patent 1s:-

1. In means for the purpose set fort-h, the combination of a stovehaving a burner ring including a conduit; said ring having outletstherein, hollow nibs arranged in staggered relations within the conduitand having apertures that register with the outlets of the ring; saidnibs being conical shaped in cross-section, a conical vent communicatingwith some of the nibs of the conduit, a chimney in direct communicationwith the vent and having a seal forming a chamber therein and also adraft passage whereby gas that enters the chamber will be forced bydraft through the passage.

2. A gas burner ring comprising a conduit, a gas inlet, projectionsarranged within the conduit and in communication with outlets formed inthe burner ring, a vent adapted to communicate with the interior of theburner, and means arranged in communication with the vent for precludingreturn of unburned gas to the burner ring.

3. In a safety appliance for gas burners, the combination of a burnerring having a conduit and outlets arranged therein, nibs secured on thering, a vent communicating with the interior of the burner and exteriorof the nibs, a conduit communicating with the vent and entering achimney, a seal that provides a chamber in the chimney to con line thecontents of the conduit and draft means for conducting the contents ofthe chamber into the draft pipe of a stove.

4. In a safety appliance for stoves and the like, the combination of aburner ring having outlets therein, a conduit in the burner, means fordirecting the flow of gas to the outlets to be ignited, said means beingfurther adapted to prevent the flow of gas that is not ignited to theoutlets and means for carrying off the unburned gas comprising a chimneyhaving a seal that produces a chamber and means for conducting gas fromthe chamber.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
